SAFE on VAULT WALL.

Specification of Letters mam.

Patented Aug. 18., 1922.

Application flle'd November '15, 1918. Serial No. 262,636.

vwalls for safes or vaults which are constructed of manganese steel orother metal which cannot be machined and which are formed in separatewall plates or sections arranged edge to edge andsecured together.

The .object of .my invention is to provide a wall structure of novel,simple and efficient construction, wherein the wall plates thereof aresecured together by a novel means which will efiectually prevent bothlateral and edgewise displacement of the wall plates relatively to eachother, and which will permit the parts to be assembled in a manner todraw the opposing edges of the plates together and retain them in closecontact with each other.

With the above and related objects in view, my invention consists in thenovel construction and combinations of parts hereinafter fully describedand particularly claimed.

In the accompanying drawings, illustrating my invention,

Figure 1 is a perspective view of a part of the meeting portions of twowall plates for a safe or vault, made in accordance with my invention,showing the studs thereon before they are riveted in the connectingplates.

igure 2 is a similar view, including a series of connecting plates andshowing the studs riveted in holes in the connecting plates.

Figure 3 is a view similar to Fig. 2, showing a continuous connectingplate instead of a series of connecting plates.

Figure 4 is a section, on line 44 of Fig. 2, showing the positions ofthe assembled parts before the studs are riveted in the holes in theconnecting plate.

Figure 5 is a view similar to Fig. 4, after the riveting operation.

Referring to the drawings, 2 and 3 designate two adjacent wall plates,and 5 and 6 connecting plates for the wall plates 2 and 3.

The plates 2 and 3 are adapted to form parts of the top, bottom or sidewalls of a safe or vault. The adjacent-edge portions of the plates 2 and3 abut against each other,

and the edge portion of the plate '2 is provided with a central,longitudinally-extending rib 7 which is fitted zinto a central, longitudinally-extending groove 8 in the adjacent edge portion of the plate3. The plates 2 and '3 are usually formed of unmachinable metal, such asmanganesesteel, and theedge portions thereof are finished to fit againsteach other by "suitable grinding operations,

well known to persons skilled in this'art.

The-wall plates 2 and 3'are provided with pro eating pins or studs-9{and 10, respec- =t1ve y, arranged at intervals along the meetang edgeportions of t1 plates. These studs 9 and 10 are formed or cast integralwith the plates 2 and 3, and the studs 9 and 10 project from the innerfaces of the plates 2 and 3.

Arranged against the inner faces of the wall plates 2 and 3 are a numberof suitably spaced connecting plates 5, as shown in Figs. 2, 4 and 5,which cross the joint between the plates 2 and 3, and which may beformed of any suitable material, preferably machinable metal. The studs9 of the plate 2 are paired with the studs'lO of the plate 3, and aconnecting plate 5 is provided for each pair of studs. The connectingplates 5 are provided with counter-sunk holes 11 and 12 into which thestuds 9 and 10 extend, as clearly shown in Fig. 4.

In. assembling the parts, the rib 7 of the plate 2 is entered into thegroove 8 of the plate 3, and the adjacent edge portions of the plates 2and 3 are brought into contact with each other, as clearly shown in thedrawings. The connecting plates 5 are then placed against the innerfaces of the wall plates 2 and 3, as shown in Fig. 2, with the studs 9and 10 projecting through the holes 11 and 12, as shown in Fig. 4. Thisbeing done, the projecting ends of the studs 9 and 10 are riveted in thecounter-sunk holes 11 and 12 of the plates 5, as shown in Figs. 2 and 5.During the riveting operation, the blows are struck against the ends ofthe studs 9 and 10, in the directions of the arrows, shown in Figs. 4and 5, thereby displacing the studs 9 and 10 toward each other and thusdrawing the abutting edge portions of the plates 2 and 3 into closecontact with each other through the medium of the studs 9 and 10 and theconnecting plates 5, and forming a very tight joint between the wallplates 2 and 3.

In Fig. 3 of the drawings, I have shown one continuous connecting plate6 instead of the series of plates 5, shown in Fig. 2. The continuousconnectlng plate 6 extends the full length of the joint between the wallplates 2 and 3 and it is provided with spaced holes in which all thestuds 9 and 10 are riveted, as a means of securing it to the wall.

plates.

In order that the full thickness of the connecting plates 2 and, 3 shallnot. extend into the, interior of the safe or vault beyond the plane ofthe inner vfaces of the unain bodies of the wall plates, I provide thewall plates 2 and 3 with offset portions 13, andl l inthe region of thejoint between the plates for the reception of portions of the connectingplates 5 and 6 asclearly shown in the drawings.

hen the parts are assembled, as hereinbefore described, a jointbetween'the wall plates 2 and?) is provided which is strong and durableand which :cannot be opened 7 from the outside of the safe or vault; anda joint is provided in which relative lateral and edgewise dispbcementor the wall plates 2 and 3 is prevented by the combined action of theconnecting plates 5, the studs ,9 and 10,

nally extending rib projecting into a longitudinally extending groove.in the edge portion of the other plate and preventing lateral separat onofthe .plates,'and a connect ng plate arranged against the lnnersurfaces'o'f the wall plates and crossing thejoint between them, theconnecting plate being secured to the wall 'platesby, studs "formedintegral with the wall plates and riveted in holes in the connectingplateand preventing ed ewise separation ofthe wall plates. 7

in testimony whereof I atfix my signature hereto,

I ANTHONY KENNEDY.
